From wood protection to health protection: larvicidal potential of formulations containing Sextonia rubra wood residues extract against Aedes aegypti mosquitoes
2020 - IRG/WP 20-10968
French Guiana is a French overseas territory almost entirely covered by Amazonian rainforest and characterized by its incredible biodiversity. Several woody species harboured by this tropical forest are exploited sustainably for timber industry. They are commercialized notably for carpentry and outdoor applications because of their remarkable natural durability. Among them, stand Dicorynia guianen...

Copper-octanoate - a potential reference preservative replacement for CCA in field test standards?
2022 - IRG/WP 22-20688
Finding a CCA reference replacement for use in standardised test methods is of high priority since this chemical is being phased out and may in the near future be banned also for experimental and approval purposes. In this paper we assess the possibility to replace CCA reference preservative with an historical copper octanoate product. There is a huge amount of lab and field test data available fo...

A new approach to wood protection: Potential of biologically synthesised CuO and ZnO nanoparticle formulation as a wood preservative
2022 - IRG/WP 22-30758
Even though metal nanoparticles are effective in protecting wood, they are less preferred, as they are synthesised using methods which are expensive and are not environmentally friendly. Biological synthesis of nanoparticles using plants, fungi, yeast, bacteria and viruses, has been accepted as an alternative approach and is referred to as green synthesis. Utilization of biologically synthesised n...

Unlocking the potential of tropical fast-growing hardwood species
2023 - IRG/WP 23-11010
Social forestry or community managed forestry practices have been promoted as an inclusive way to mitigate climate change through the framework of the UNFCCC scheme of the Reduce Emission Deforestation and forest Degradation (REDD+) programme. Fast growing wood species are one of the least tapped social forestry commodities in Southeast Asia, and they have the potential to be upscaled to meet the ...

Potential of plant polyphenol extracts in pesticide formulations against Xylophagous insects
2023 - IRG/WP 23-30790
Termite castes (soldiers, nymphs, and reproductives) are unable to feed themselves and are fed via trophallaxis from the workers which degrade the cellulose from wood. It is of great economical importance to ascertain the efficacy of preservatives against wood decay organisms in order to extend wood products service life. Remedial chemical product applications are used primarily as wood treatments...

Unlocking the potential of paulownia in Malaysia: Durability assessment to mold
2024 - IRG/WP 24-11043
Paulownia is one of the species included in the plantation program in Malaysia due to its fast growth (three to four years) and excellent properties suitable for wide application including furniture, biofuel, musical instruments, and decoration. However, data on its durability to biodegradation is scarce, especially for tropical usage. In this study, a paulownia clone known as Revotropix Paulownia...

Potential of heartwood extracts as wood preservatives combined with linseed oil in 8-year above-ground and in-ground field trials
2024 - IRG/WP 24-20719
The current study assessed the efficacy of heartwood extracts from Tectona grandis, Dalbergia sissoo, Cedrus deodara, and Pinus roxburghii, combined with linseed oil, as protectants for two non-durable wood species against termites and decay fungi. Stakes measuring 45.7 × 1.9 × 1.9 cm and blocks measuring 12.5 × 3.75 × 2.5 cm of the sapwood of southern pine (Pinus sp.) and cottonwood (Populus ...

The potential of Wacapou (Vouacapoua americana) extracts to develop new biobased protective solutions for white woods
2024 - IRG/WP 24-20724
The valorisation of Amazonian wood residues into active chemical compounds could be an eco-friendly, cost effective and valuable way to develop wood preservatives formulations in order to enhance the decay and termite resistances of low durable wood species, by impregnation processes. Wacapou (Vouacapoua spp., Fabaceae) is a well-known Guianese wood species for its use in local wood construction ...

Evaluating the potential for re-using timber from deconstructed sea defence groynes from the Bournemouth groyne field
2024 - IRG/WP 24-50397
In the shadow of a looming climate crisis, the modern age construction industry is evolving. The for implementing sustainable practices has never been greater and the potential role of the circular economy is front and centre. It can play a pivotal role in transforming the industry by promoting sustainable practices which emphasise the need to reduce consumption of natural resources. Re-using timb...
